Specification of Letters Patent.

Patented Jan. 7, 1919.

Application filed January as, 1915. Serial No. 3,969.

To all whom it may concern:

Be it known that I, HUGO O. STAMP, a citizen of the United States, residin at Milwaukee, in the county of Milwau cc and State of Wisconsin, have invented certain new and useful Improvements in Concrete- Mixer Loaders, of which the following is a specification.

The present invention relates to new and useful improvements in conveying apparatus wherein the various conveyer sections are relatively movable to engage the material to be conveyed, and the invention is more par ticularly directed to ,the provision of a loading machine adapted for use in connection with concrete mixers.

In various concreting operations on a relatively large scale, piles of certain of the ingredients of the concrete, or aggregate, are dumped at points adjacent the concrete mixing machine, and in road paving operations the aggregate is dumped in piles along the road-way in advance of the mixing machine. A considerable expenditure of labor has been heretofore involved in conveying the aggre gate from the various piles to the mixer.

It is primarily the object of the present invention to provide an apparatus whereby the aggregate may be mechanically conveyed from the various piles to the mixer, and inasmuch as the aggregate in road paving operations is usually disposed in relatively long piles extending longitudinally at the sides of the road it is more particularly an object to provide a conveying apparatus which will operate over relatively large areas Without changing the position of'the body portion of the apparatus. In view of the comparativerapidity at which road-paving operations proceed, it is necessary to procure a frequent shifting of the concrete mixer and consequently of the loading machine, in some operations this shifting occurring about once every twenty minutes, and it is therefore also an important object of the invention to provide a loading machine which is exceedingly mobile to provide for frequent shifting movements, and to provide for its transportation generally.

The present accomplishment of the foregoing operations by the provision of a main longitudinal conveyer means and lateral conveyers movable longitudinally thereof and arranged to disveyers.

invention contemplates the charge thereon, and it is further an object of the invention to provide an arrangement in which the lateral conveyers are capable of horizontal pivotalmovement whereby they are adapted to engage all portions of an elongated pile of aggregate to conve the contents thereof, it being more speci cally the object to provide an arrangement whereby the lateral conveyer members may be manipulated for horizontal movements from a single central point to procure actuation thereof in their various longitudinal posi tions along the main conveyer means.

Another object resides in the provision of a mounting for the lateral conveyer members whereby they may move vertically relative to the main conveyer means, to compensate for possible irregularities in the ground over which they travel.

Concrete aggregate usually comprises sand and gravel and in the operation of the present machine, one of the elongated piles at the side thereof would comprise sand and the other pile would comprise gravel. In concreting operations it is essential to procure definite relative proportions of these different ingredients conveyed to the mixer and in differing instances these proportions must be varied, these variations often being'necessary at different times during a single concreting operation. It is therefore another important object of the present invention to provide an independent measuring means associated with .the discharge of each of the lateral conveyer members, whereby the relative desired amounts of material conveyed may be determined, and it is in this connection further an object to provide a means for adjusting the measurin means.

A moredetailed object o the invention resides in the provision of a common drive means for both the lateral conveyer members, whereby an economy of structure is procured and further whereby a single tightening device may be utilized to assure proper cable tension with respect to the lateral con- In this connection it is also an object to provide an arrangement wherein the direction of travel of the cable portions in engagement with the lateral conveyers is always the same whereby the drive cable in addition to operating the elements of the conveyers also serves to urge the conveyers toward one end of the machine.

movable to permit tilting movement of the skip in dumping into the mixer, and which is further automatically movable back .to operative position upon the skip being lowered into receiving position.

A furtherobject resides in the provision of a machine .which may be manipulated for all its conveying and measuring operations, in the manner broadly heretofore set forth, from a single point and bya single operator.

Referring now more particularly to the accompanying drawings, the loading machlne illustrated in Figs. 1 ,to 7 thereof, comprises an elongated wheeled body frame 1 which carries a longitudinal conveyer belt B arranged to discharge at one end of the frame and to receive the discharge of hoppers C mounted on carriages independently movable longitudinally of the frame and each carrying a downwardly'extendlng lateral conveyer D for filling the hoppers from piles of aggregate disposed at the this connection.

H of Fig. 2 and showing the conconveyers and for dumping the hoppers are all disposed at one end of the machine.

The main frame comprises channeled side sills 10 and a central sill 11 connected by the plurality of transverse sills 12 which are grouped adjacent the ends of the frame. Wheeled axles 13 are'carried by brackets 14' depending from the ends of the frame, and one of these axles is preferably steerable although no specific structure is shown in chiefly as a track for the hopper carriages and terminates at the innermost cross sills l2.

Inasmuch as the lateral conveyer structures are similar, only one will be described and the numerals applied thereto are equally applicable to both.

The carriage of each lateral conveyer mechanism comprises a U-shaped frame 15 at the ends of the arms of which are carried wheels 16 mounted on the corresponding side sill and the central sill and flanged to retain their engagement therewith. ,Carried within the frame 15 is a hopper 17 having its outer side wall inclined inwardly toward its bottom whereby the hopper may discharge well inwardly of themachine onto the main conveyer.

For supporting and driving the lateral conveyer associated with this hopper, a bracket 18 of inverted U-shape is carried at the inner side of the frame 15 and from the upper portion of this bracket, an arm 19 extends diagonally over the frame toward the forward end of the machine and forms a bearing at its free end for one end of a lateral conveyer shaft 20 which has its other end journaled in a bearing 21 on a bracket 22 upstanding from'the outer side of the frame. 'At its angle adjacent the corner of the hopper the bracket arm is provided with a pair of upward and a pair of downward projections 26 which carry pairs of opposed pulleys 27 and pivoted to the bracket arms centrally between the pulleys is a horizontally swingable knuckle 28 to which is pivoted for vertical movement a lateral conveyer frame comprising side bars 29 between the outer ends of which is mounted an idle sprocketwheel 30, a drive sprocket wheel 31 is carried on the shaft 20, and trained about these sprocket Wheels- The central sill 11 serves and lower stretches of the chain passing between corresponding pairs of rollers 27 and held therebetween to effect proper operation of the chain upon horizontal swinging movement of the lateral conveyer frame which is permitted a universal pivotal movement. To support the outer end of the frame. transverse bars 34 are secured thereto, adjacent its outer end and extend at the rial from a pile of aggregate and to convey it to the hopper. By reason of the universal pivotal Connection of its frame, the lateral conveyer may move vertically to compensate for irregularities in the ground over which it travels and may also' move horizontally whereby to engage all parts of the pile of a gregate.

For effecting axis horizontal movement of the lateral conveyer in various positions thereof, a shaft 38 is extended longitudinally of the machine adjacent the intermediate portion of the inclined outer side of the hopper and journaled at its ends in the innermost cross sills 12. Splined on this shaft isa pulley 39 which is rotatably held for movement with the lateral conveyer carriage by a bracket 40 upon the side of the hopper. A pair of idle pulleys 41 are mounted on a common stub shaft 42 secured to the upper portion of the hopper above the pulley 39 and at the three corners of the frame are mounted pulleys 43, a cable 44 is trained about the shaft actuated pulley 39 and about the idle pulleys 41 and about the pulleys 43 at the corners of the frame and the ends of this cable are secured to a transverse bar 45 fastened to the lateral conveyer frame adjacent its inner end, the outer Side of the bar being extended a considerable distance from the frame whereby a proper leverage is afforded to swing the frame horizontally upon pulling the cable. By the foregoing arrangement the lateral conveyer may be swung horizontally in its various positions along the machine by rotating the shaft 38. This shaft 38 is controlled, in common with various other operating members hereinafter described, from a common point at the forward end of the machine, and to provide bearings for various shafts associated with these control means, an upstanding frame 46 of inverted U-shape is carried adjacent the forward end of the machine and has extending from its sides, forwardly and downwardly extending angular bars 47 connected adjacent their angle by a transverse bar 48. The shaft 38 is controlled by a shaft 49 having a bearing in one of the sides of the frame 46 and in the transverse bar 48, this shaft 49 carries at its forward end a hand wheel 50 and has a sprocket connection 51 with the shaft 38. Thus rotation of thehand Wheel 50 will swing the lateral conveyer horizontally to engage different portions of the pile of aggregate. I

For moving the carriage longitudinally of the machine. a shaft 52 is journaled transversely on the angular bars 47 and loosely various positions along t mounted on this shaft is a handwheel 53 having sprocket teeth on its hub, a sprocket chain 54 is secured at one end to the forward end of the inner side of the carriage and extends forward of the machine and about an idle pulley 55, and then upwardly and about the sprocket wheel 53 and then downwardly.

about a pulley 56 disposed below the pulley 55 then rearwardly and about the idle pulley 57 at the rear end of the machine and finally forwardly for securement to the rear end ofthe frame. wheel 53, the carriage and consequently the hopper and lateral conveyer are shifted longitudinally of the machine.

The. hopper is provided with a dump bottom comprising two sections 58 hinged at the outer sides of the hopper, and to provide a means operable from the forward end of the machine for dumpin the hopper in its e machine, a shaft 59 is journaled transversely on one end of the hopper and this shaft carries a crank arm 60 to which is secured the upper end of a span link 61 having chains 62 securedto its lower end and to the bottom sections of the hopper. The shaft 59 extends inwardly of the hopper and carries on its inner end a pulley 63. Loosely mounted on the shaft 52 at the forward end of the machine is a Thus upon rotating the hand i and trained about this sprocket hub is a sprocket chain 65 which extends downwardly thence about an idle pulley 66 and rearwardly to the rear end'of the machine, thence forwardly and about the pulley 63 on the shaft 59,, thence forwardly and about an idle pulley 68 and finally upwardly and about the sprocket hub of the hand wheel 64. Thus upon rotating the hand wheel, a movement of the shaft 59 will be effected toopen or close the bottom of the hopper, it being noted that during the movements 0 the hopper toward the forward end of the machine, its bottom will be held closed and the hand wheel 64 will rotate idly.

To drive the lateral conveyer, a beveled gear wheel 69 is carried on the inner end of the shaft 20 and meshes with a beveled gear 70 which is carried on a shaft 71 journaled at, the intermediate portion of the bracket arm 19 and at the upper portion of the intion of this clutchin the various positions of the carriage, a longitudinal shaft 7 5 18 provided having its forward end journaled in an upper corner of the frame 46 and 9 portion a drum 81.

carrying a crank handle 7 6 whereby it may be rotated, and having its rear end j ournally supported by an upstanding bearing frame 77 at the rear end of the machine, the shaft being disposed under the clutch member, and having splined' thereon a clutch yoke 78 embracing the clutch member and properly held with relation thereto by its confinement between bearing arms 79 extending downwardly from the bracket 18 to embrace the shaft 75. Thus upon reciprocating the crank handle 76, the operation of the lateral conveyer may be controlled.

Each of the lateral conveyers and its associated mechanism is thus adapted for entirely independent operation.

Transversely mountedpnthe body frame rearwardly of the upstanding bearing frame 77 is the main drive shaft 80' of the machine which may receive its power from any suitable source as by an engine carried on the frame. This shaft carries at its central A second drum 82 is mounted on a transverse shaft 83 journaled on the bearing frame 77 and disposed adjacent the first drum, and associated with these drums and with both of the drive sheaves 72 of the lateral conveyer structures is a common cable 84 which extends from the top of the drum 81 over the drum 82 then under the adjacent guide over the drum 82 then under the adjacent guide sheave 73 of one'of the lateral conveyers over the drive sheaf 72 under the other guide sheave 73 thence forwardly around a pulley 85 at the forward end of the machine, thence rearwardly around an idle pulley 86 mounted on the shaft 83 at the rear end of the machine, thence forwardly under the adjacent guide sheave 73 of the other conveyer member, thence over the drive sheave 72 of said other conveyer and under the other guide sheave 73 thence forwardly and around a vertical idle pulley 87, thence rearwardly around the drum 82 and finally the cable is given a number of turns on both the drums 81 and 82 whereby its proper frictional engagement therewith is assured.

Thus those portions of the cable which engage the drive sheaves 72 both drive in a orward direction and in addition to op erating the lateral conveyers, the frictional engagement of the various sheaves with these cable portions serves also to advance the conveyers and their associated mechanisms whereby they are at all times urged to proper operative engagement with the piles of aggregate.-

The pulleys 85 and 87 which carry the (-able loops of the drive sheaves 72 are provided with a common adjusting means to procure desired tension of the cable and to accomplish this, an upstanding bearing frame 88 is carried by the central sill 11 of the main frame inwardly of and adjacent the bearing frame 46 and carriedby these frames are a spaced pair .of shafts 89 on which are slidably mounted bearing sleeves 90 formed at the arms of a U-shaped carriage 91. The vertical pulley 87 is disposed between and journally connected with the arms of this carriage and the horizontal pulley 85 is journaled on the bight of this carriage. Fixedly secured to the bight of the carriage is the shaft 92 which is projected through a transverse bar 93 on the frame 46 and an adjusting wheel 94 is threaded on the outer end of this shaft to thus hold the carriage against movement and to consequently hold thecables under desired tension.

.The main conveyer comprises a broad endless belt 95 having sprocket chains 96 at its sides which at one end of the conveyer are trained about the sprocket wheels 97 carried on a shaft 98 which is journaled in brackets 99 projected from the end of the body frame. At the other end of the conveyer, the chain and belt are trained about idle wheels 100 carried by a shaft 101 which is in turn carried by a pair of side 9 extensions of the front axle brackets 14.

The upper stretch of the main conveyer belt is supported by rollers 104 carried by the side bars 102 and immediately forwardly of the rear axle 13 of the body frame, guide rollers 105 are disposed over the sprocket chains 96 of the belt whereby the major 7.

portion of the belt is held in horizontal position, with its rear portion inclined upwardly, idle rollers 106 being disposed between the stretches of the belt adjacent the rear axle to guide the lower strip of the belt.

Appreciating that the manual operation of conveying aggregate from the piles to the mixer is divided into two steps, that of loading the usual wheelbarrows, and of trundling said barrows to the mixer, it is seen that the lateral conveyers D of my machine are the mechanical equivalent of the barrow loading step, while the main conveyer B is the mechanical equivalent of the trundling step of the complete conveying operation, and inasmuch as the barrows in the manual operation were utilized to measure the aggregate, number of barrow loads so the hoppers C serve to more accurately measure the aggre gate in my machine. Thus, while it is highly desirable to use the lateral conveyers to mechanically discharge the loading function, it may be under certain conditions ad visable to eliminate said lateral conveyers whereby the machine would effect mechanimeagre? cally the main conveying step, the hoppers being loaded manually.

To provide an arrangement whereby the loading skip of a concrete mixer designated at X in Fig. 7 may be permitted its usual free movement to dump into the mixer, the brackets 99 are extended past the main conveyer shaft 98, and are downwardly inclined therefrom and carry at their free ends a shaft 110 on which is fixedly secured a chute plate 111 projecting inwardly of the edge of the skip. An arm 112 projects downwardly from the central portion of the shaft at approximately a right angle to the chute plate, andv at one side of the shaft 110, an arm 113 projects rearwardly therefrom carrying a weight 114. The plate is normally disposed in its inclined position to discharge into the skip, being held against rotation by a stop arm 115 on the shaft engageable with one of the brackets 99. When the skip is raised to procure its dumping operation, it engages the plate 111 and swings it upwardly. In this move, the weight arm 113 swings inwardly of the dead center afforded by the shaft 110 and the arm 112 moves rearwardly into the path of the skip, rotation of the shaftin this direction being limited by engagement of a stop arm 117 carried thereby, with one of the brackets 99. Thus upon return movement of the skip to its loading osition it will engage the arm 113 and trip t he shaft whereby the arm 113 will be swung rearwardly of its dead center and the plate permitted to fall to its operative position.

Fig. 7 shows'the operative position of the present machine between two piles of. aggregate Y and in advance of the mixer M. In operation, the lateral conveyers are manipulated to engage their corresponding piles of aggregate. Thus, in operation both of the lateral conveyer members are actuated simultaneously. Upon the smaller hopper being filled, the operator stops the corre-- sponding conveyer by shifting the clutch 74; thereof and the other lateral conveyer continues in actuation until the larger hopper is filled at which time both of the hop pers are dumped in the manner heretofore set forth and the operation is repeated. Thus difierent relative amounts of aggregate inedients maybe conveyed. Inasmuch as it is necessary to vary the relative proportions of material conveyed, an independent adjusting means for the contents of the hoppers is provided which comprises in connection with each hopper, a transverse partition plate 118 selectively engageable between corresponding pairs of a plurality of series of pins 119 within the hoppers.

' It may in some instances be desired to use the present machine in connection with that type of concrete mixer designated at M in Fig. 9 and provided with a stationary loadin hopper L, divided into two sections 121 an having then tops disposed at a consider able elevation. v To adapt the machine for this type of mixer, the main conveyer is provided in two sections B each adapted at its rear end to discharge into a corresponding hopper section 121 and in this form, the hoppers 17 of the carriages are eliminated and last lateral conveyer discharges directly on to its corresponding conveyer section B.
